A 'mockbuster' from the Asylum company, who specialise in making films that have a startling similarity to a current big-budget production, usually of the horror/monster variety.
Eric Roberts has been spliced into this one, featuring in a number of scattered scenes apparently alone, although joined by other cast members toward the end.
There's not a huge amount to say about this that isn't obvious. The effects are variable, with the 'monster' appearing less but more impressively than the 'ape', who has the characteristics of a chimp - more cuddly than menacing. There's a passing plot regarding aliens and UFOs, purely to explain the outsized nature of the beasts, which isn't expanded upon.
The results are a curious mix of styles: a film made for youngsters, but one that is filled with long scenes of people talking that would surely bore younger viewers. The creatures are only briefly shown. My score is 4 out of 10.
